Abstract:
采用自由基溶液共聚合法,合成了系列磺酸基丙烯酸酯三元无规共聚物表面活性剂(APSA).利用FTIR、1H-NMR、13C-NMR、GPC及元素分析证实了APSA的结构及组成.APSA胶束为核壳结构,随磺酸基含量增加,亲水层增厚.低剪切速率下,APSA溶液的黏度随磺酸基含量的增加而增加,胶束间的相互作用增强,假塑行为增强;高剪切速率下,黏度基本保持一致.DLS和表面张力表明,APSA1可将水溶液的表面张力降至43.26mN/m.随亲水基团增加,表面张力增加,临界胶束浓度(cmc)增加.溶液浓度在cmc以下时,光散射强度较低且变化缓慢,高于cmc后,光散射强度呈现急剧的线性增长趋势,胶束聚集数急剧增加.随溶液浓度和亲水基团增加,胶束尺寸和分布系数增加.荧光光谱表明,随APSA浓度增加,I1/I3值从1.8降低到约1.2,芘的(0,0)吸收峰从334nm迁移到338nm,I338/I334值从0.7增大到1.45,表明疏水基团聚集形成疏水微区,芘分子从水相极性环境转移到胶束疏水内核.随亲水基团含量增加,分子聚集形成胶束的难度增加,速率降低.
